We just upgraded our system to vB 3.8.6 as well as upgrading from vBa CMPS 2.x -> CMPS 3.0 RC1 and Photoplog 2.1.4.4 -> Photoplog 2.1.4.6. We'd been running GARS 2.1.8b for a while before upgrading all the rest.

We ended up pulling an all nighter ironing out the kinks with our revised site navigation system and we DID have a conflict between CMPS 3.0 RC 1 and vBSEO (easily fixed by changing the execution order of one of the vBSEO plugins so it ran *after* CMPS finished doing what it needed to).
